Are Saunas the Next Big Performance- Enhancing “Drug”? Preface by Editor. This post will explain how heat can be used to increase growth hormone, muscular hypertrophy, endurance, and otherwise aid performance. It’s authored by Rhonda Perciavalle Patrick, Ph. D, and it’s comprehensive. But before we get started, you need to read some background and warnings. On a few occasions, I’ve been hospitalized for heat stroke symptoms, and the symptoms hit suddenly and without warning. I’m extremely lucky I didn’t smash my skull on the ground after the collapses. To delve into this handicap, I even became a test subject at Stanford University in 2. I underwent military- related heat marches to exhaustion, capturing data the entire time. Here are some choice pics. It was as fun as it looks (I’ll share videos another time, as they’re hilarious): After each session, I was so incapacitated that I couldn’t do any work for 8- 1. I often had to simply go home and sleep, even at 1. These issues led me to eventually leave the study. Heat is serious fucking business, m’kay? People can die from excessive heat (sauna example here, recent running death here), so read these warnings carefully.
It would make us both quite unhappy. Consult a doctor before doing anything described in this post or on this blog.

OK, will all that out of the way, here we go. Consider looking at this piece as what elite athletes are likely to augment to their training and drug regimens. The following is a guest article by Rhonda Perciavalle Patrick, Ph. D., who works with Dr. Bruce Ames of the Ames carcinogenicity test, the 2. Patrick also conducts clinical trials, performed aging research at Salk Institute for Biological Studies, and did graduate research at St. Jude Children’s Research Hospital, where she focused on cancer, mitochondrial metabolism, and apoptosis. Enjoy! And if you have any experiences with using heat, cold, or other environmental factors to improve performance; or if you’ve suffered from them; I’d love to hear about it all in the comments. Ditto for any factual corrections. Enter Rhonda. For the most part, people don’t like to get hot. The massive indoor climate control systems and pleasantly chilled water fountains found in most gyms speak to this fact. There are some exceptions — Bikram yoga, for example — but they’re few and far between. But here’s the surprise: increasing your core temperature for short bursts is not only healthful, it can also dramatically improve performance. This is true whether it’s done in conjunction with your existing workout or as an entirely separate activity. I’m going to explain how heat acclimation through sauna use (and likely any other non- aerobic activity that increases core body temperature) can promote physiological adaptations that result in increased endurance, easier acquisition of muscle mass, and a general increased capacity for stress tolerance. I will refer to this concept of deliberately acclimating yourself to heat, independent of working out, as “hyperthermic conditioning.”I’m also going to explain the positive effects of heat acclimation on the brain, including the growth of new brain cells, improvement in focus, learning and memory, and ameliorating depression and anxiety. In addition, you’ll learn how modulation of core temperature might even be largely responsible for “runner’s high” via an interaction between the dynorphin/beta- endorphin opioid systems. The Effects of Heat Acclimation on Endurance. If you’ve ever run long distances or exercised for endurance, it’s intuitive that increased body temperature will ultimately induce strain, attenuate your endurance performance, and accelerating exhaustion. What might not be as intuitive is this: acclimating yourself to heat independent of aerobic physical activity through sauna use induces adaptations that reduce the later strain of your primary aerobic activity. Hyperthermic conditioning improves your performance during endurance training activities by causing adaptations, such as improved cardiovascular and thermoregulatory mechanisms (I will explain what these mean) that reduce the negative effects associated with elevations in core body temperature. This helps optimize your body for subsequent exposures to heat (from metabolic activities) during your next big race or even your next workout. Just a few of the physiological adaptations that occur are: Improved cardiovascular mechanisms and lower heart rate. Lower core body temperature during workload (surprise!)Higher sweat rate and sweat sensitivity as a function of increased thermoregulatory control. Increased blood flow to skeletal muscle (known as muscle perfusion) and other tissues. Reduced rate of glycogen depletion due to improved muscle perfusion. Increased red blood cell count (likely via erythropoietin). Increased efficiency of oxygen transport to muscles. Hyperthermic conditioning optimizes blood flow to the heart, skeletal muscles, skin, and other tissues because it increases plasma volume. This leads to endurance enhancements in your next workout or race, when your core body temperature is once again elevated.

Explore Yoga opened in Shreveport in 2011 and is the premier yoga studio in northern Louisiana. Being heat acclimated enhances endurance by the following mechanisms. The increased delivery of nutrients to muscles reduces their dependence on glycogen stores. Endurance athletes often hit a “wall” (or “bonk”) when they have depleted their muscle glycogen stores. Hyperthermic conditioning has been shown to reduce muscle glycogen use by 4. This is presumably due to the increased blood flow to the muscles. In addition, lactate accumulation in blood and muscle during exercise is reduced after heat acclimation. It improves thermoregulatory control, which operates by activating the sympathetic nervous system and increasing the blood flow to the skin and, thus the sweat rate. This dissipates some of the core body heat. After acclimation, sweating occurs at a lower core temperature and the sweat rate is maintained for a longer period. So what sort of gains can you anticipate? One study demonstrated that a 3. POST- workout increased the time that it took for study participants to run until exhaustion by 3. The 3. 2% increase in running endurance found in this particular study was accompanied by a 7. RBC) count. 4 This increased red blood cell count accompanying these performance gains feed right back into those more general mechanisms we talked about earlier, the most obvious of which being: more red blood cells increase oxygen delivery to muscles. It is thought that heat acclimation boosts the RBC count through erythropoietin (EPO) because the body is trying to compensate for the corresponding rise in plasma volume. Note from Tim: If “EPO” sounds familiar, it’s because it’s commonly injected by Tour de France competitors. More on that here.)In other words, hyperthermic conditioning through sauna use doesn. I do want to mention that while these gains were made with a small sample size (N=6) some of the later studies that I point out reinforce this conclusion. The Effects of Hyperthermic Conditioning on Muscle Hypertrophy (Growth)Exercise can induce muscular hypertrophy. Heat induces muscular hypertrophy. Both of these together synergize to induce hyper- hypertrophy. Here are a few of the basics of how muscle hypertrophy works: muscle hypertrophy involves both the increase in the size of muscle cells and, perhaps unsurprisingly, an accompanying increase in strength. Skeletal muscle cells do contain stem cells that are able to increase the number of muscle cells (TIM: called “hyperplasia. That’s it. At any given time your muscles are performing a balancing act between NEW protein synthesis and degradation of existing proteins. The important thing is your net protein synthesis, and not strictly the amount of new protein synthesis occurring. Protein degradation occurs both during muscle use and disuse. This is where hyperthermic conditioning shines: heat acclimation reduces the amount of protein degradation occurring and as a result it increases net protein synthesis and, thus muscle hypertrophy. Hyperthermic conditioning is known to increase muscle hypertrophy by increasing net protein synthesis through three important mechanisms: Induction of heat shock proteins. Robust induction of growth hormone. Improved insulin sensitivity. Exercise induces both protein synthesis and degradation in skeletal muscles but, again, it is the net protein synthesis that causes the actual hypertrophy. When you exercise, you are increasing the workload on the skeletal muscle and, thus, the energetic needs of your muscle cells. The mitochondria found in each of these cells kick into gear in order to help meet this demand and start sucking in the oxygen found in your blood in order to produce new energy in the form of ATP. This process is called oxidative phosphorylation. A by- product of this process, however, is the generation of oxygen free radicals like superoxide and hydrogen peroxide, which is more generally referred to simply as “oxidative stress”. Heat Stress Triggers Heat Shock Proteins That Prevent Protein Degradation. Oxidative stress is a major source of protein degradation. For this reason, any means of preventing exercise- induced oxidative protein damage and/or repairing damaged proteins, while keeping the exercise induced protein synthesis, will ultimately cause a net increase of protein synthesis and therefore will be anabolic. Heat shock proteins (or HSPs), as the name implies, are induced by heat and are a prime example of hormesis.
